Circuit-connector.



iThoughv I -have herein shown bothcontadts of each pair as being movable withlrespect to the-contact carrier therefor .I do not wish to be limited to this arraffgetinuing menibers in mechanical assembly while these' members are electrically. separate, I do not wish to be limited to a oon- Itructioh in which the'contact members of a pair of contacts are adaptedto the function of conducting current as well as to the'periormance of the stated mechanical function, this double function obtaining when the structure is embodied in a double pole arrangement to which the invention is not to be limited. WhileI have shown an arrangement in which the plug 15 is adapted to be placed in inner and outer positions for the purpose of including'the lamp in and exclud mg it from circuit, I do not wish to be limited to this arrangement, it being apparcut that mechanical separation between the contact 5 and the contact carrier lfiis not essential to the realization of all of the advantages of my invention. 3

Thou h the contacts of each pair 4, 5, 6, 7 are 5 own in sliding engagement, I do not wish to be limited to this arrangement since the interposed spring 22 or other means could be relied upon for bringing the contacts between which such spring is interposed into electrical connection without relying upon the engagement between such contacts.

While I have herein shown and particularly described the preferred embodiment of my invention I do not wish to be limited to the precise details ofconstruction shown as changes may readily. be. made without defiarting from the s irit of my invention, but

ng thus descri d my invention I .claim' as new and desire to secure by Letters Patent the following:.- 1

1.. A connector including a shell; a air euit continuing member within each end of the shell; two pairs, of contacts within the shell one contact of each pair engaging one circuit crmtinuing member and the ()tl'lf'! contact of each pair engaging the other circuit continuing member: and a spring interposed between the contacts of each pair for maintaining them. in engagement with the circuit: continuing members, one of said circuit continuing members and the shell having inteirngaging coupling formations serving to position this circuit ,continumg member in inner and outer positions respectively to makef'and break-circuit, acontact, of one pair. pressed toward this circuit coritinuing member having means for stopping its movementafter this circuit continuing l'nemlmr has left itsiimer position and beone contact of e: ch

fore it reaches its outer position, while a. 1 contact, of theoher pair, lsmamtained in engagement with this circuit continuing h member by its siring in both positions of this circuit continuing member.

2. A connector including a shell; two pairs of contacts within the shell Bill! engaging one circult continuing nem r and the other contact-of each pair engaging the other circuit continuing member; a carrier within the member in inner and outer positions respecshell. for these on atacts; and a spring interposed between the contacts of each pair for maintaining. then in engagement withv the circuit continuing: members, one of said circuit continuing members and the shell having interengagiig -co1.|pling' formations serving to position this circuit continuing tively to make and break circuit, a" contact, of one pair, pressed toward tlnscircuit continuing member having means for stopping its movement after this circuit continuing member hasleft its inner position and before it reaches ts outer position, while a contact, of the other pair, is maintained in engagement with this circuit continuin member by its. spring in both positions 0 this circuit contil uing member.

A connector includin a shell; a circuit continuing memlier coup ed with the" shelland carrylnr two contacts; two additional contacts wit in't 1e shell each for engaging;

one of the afores rid contacts; and a spring pressing each acditional contact into ongagement wlth it; complemental, contact on said circuit continuing member, said circuit continuing member and the shell having intercnguigmg. coupling formations serving to position this circuit continuing member in.lnner and outer positions respectively to make and brea k circuit, one of said addi-Q tional contacts hiving means for stopping its movement bef are said circuit continuing meml'ier reaches i s outer position, while the spring pressing the other additional contact maintains this o her additional contact in engagement vvitl. this circuit continuing member in its ouler osition. M

4. A. connector inc udin a shell; ujlcircuit continuing member coup ed with the shell and carrying two contacts; two additional contacts within tl 1e shell each for engaging one of the aforesa d contacts; a spring pressing each addition ll contact into engagement movement before said circuit continuing 1o shell; a circuit .contlnulng meml er withln each end of the member reaches its outer position, whii'e the spring pressing the other additional contact maintains this other additional contact in engagement with this circuit continuin member in its outer position; and a carriel for said additional contacts which is fixed within the. shell.

In witness whereof I hereunto subscribe my name this fourth day ofApril, A. D. 1916.
